"what is your opinion on non-Western countries such as China, India, etc trying to develop more advanced machinery than the West in terms of AI, genetic splicing, etc?"
If they were attempting to develop more advanced machines in order to destroy the West once and for all, following which no more machines need be developed ever after, I would support them.
But I fear that is not their intent. Rather, they are attempting to develop more advanced machines in order to not be outpaced by the West in a machinery race that they, having accepted the worldview of progressivism, envision will go on indefinitely into the future. This I do not support.
This is why I am at present pessimistic (though I would love to be wrong) about the effectiveness of persuading enough people to conscientiously stop the development of machines. For now, I believe the only way to be sure is to use demographic shift to make humanity as a whole incapable of developing machines.
"They could do this by leveraging their control of greater amount of natural resources against the West, in effect preventing Westerners from acquiring the resources needed to develop the more advanced technology."
This will only work for a while. Sooner or later there will arise new types of machines that do not require those particular resources, at which point the resource-hoarders will suddenly find themselves outmanouevered.
